In fcoe_ctlr_els_send, we determine to be in FIP or non-FIP mode based
on fip->flogi_count, and at the 3rd unsuccessful FLOGI attempt, we fall
back to non-FIP mode.  This takes around 8 secs time. So we expect a FIP
discovery advertisement from the switch within 8 secs to not fall back
to non-FIP mode.

I think this is too less a time to give up FIP mode, as when RSTP
protocol is enabled in the switch I've seen the cases where the switch
can take a little longer than 8 secs to send a discovery advertisement,
even though the FKA_ADV_PERIOD is default 8 secs.  We can also have
problems when the switch administrator changes the default value to > 8
secs.

I think we should have reasonably high FIP FLOGI retries (10 ??) before
falling back to non-FIP mode.  

Please let me know your thoughts.

Thanks,
Bhanu
